Subject RepositoryImpl closing sessions twice on shutdown
Date Tue, 28 Feb 2012 10:00:49 GMT
Hi,
 I ran into strange issue w/ JR 2.4.0. 
On shutdown sessions are being closed twice which lead to the exception being logged as shown
below. As far as I can tell RepositoryImpl has system sessions in the list of active sessions
which is why it tries to close them twice - first time when closing all active sessions (RepositoryImpl.java:1078)
and second time when disposing workspace (RepositoryImpl.java:1090).

However I have no idea if the system session is supposed to be on the list of active sessions
or not. 
Also it seems to be related to timing - I have troubles reproducing the issue with debugger
attached to the server.

Is this known issue? Any pointers to what to look for when preventing this issue from occurring?

Thanks,
Jan
